I have a Samsung LN40A550 40" LCD TV that I purchased in June or July of 2008. I've had no complaints about it until last week. When I'd try to power it up, the red remote light and the white TV on light would flash alternatingly, and it would take 5-10 minutes for it to power up, instead of the matter of seconds that it used to take. I did some research and discovered that there are two capacitors that are nearing their end of life. Supposedly new ones are about $20, but the old ones have to be removed from the motherboard and the new ones soldered on in their place. I don't have soldering skills or equipment, nor do I want to learn on a TV. Saturday it powered up fine, but Sunday it never did. I ended up having to watch the Seahawks/Bears game on a 19" widescreen LCD monitor that I hooked up in place of the 40". That sucked.
So Sunday I researched local TV repair shops, and found one that comes to you to fix it. I spoke with the guy this morning and scheduled the repair for today at 1:30. He charges $180+ tax, so just under $200. That's much cheaper than the $800-$900 that I'd have to spend to replace it.
We'll see how the repair goes this afternoon.
